I use zsh and it's great. But the autocorrection is not smart at all. I think it is not updated at any time. So I get the following often:
dennis@ponyboy ~ % sudo aptitude search zsh zsh: correct 'aptitude' to '.aptitude' [nyae]?
nyae is nothing like "forever" or "never". I am gone insane.
Okay. Autocorrection is cool. But how do I update?
